Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
This page describes how to use coreboot on the Kontron 986LCD-M/mITX mainboard. It is maintained by Uwe Hermann.

---|---|---|---|---|---|---|---|---|
CPU | ||||||||
CPU works | OK | Intel(R) Core(TM)2 CPU T5300 @ 1.73GHz (dual core) | ||||||
L1 cache enabled | OK | CPU: L1 I cache: 32K, L1 D cache: 32K | ||||||
L2 cache enabled | OK | L2 cache: 2048K | ||||||
L3 cache enabled | N/A | |||||||
Multiple CPU support | N/A | |||||||
Multi-core support | OK | Both cores show up in /proc/cpuinfo. | ||||||

EDO | N/A | |||||||
SDRAM | N/A | |||||||
SO-DIMM | N/A | |||||||
DDR | N/A | |||||||
DDR2 | OK | Works fine, but currently you need to populate both RAM slots with DIMMs (of the same size?). | ||||||
DDR3 | N/A | |||||||
Dual channel support | N/A | |||||||
ECC support | ? | |||||||
On-board Hardware | ||||||||
On-board IDE 3.5" | OK | |||||||
On-board IDE 2.5" | N/A | |||||||
On-board SATA | OK | Tested: SATA disk (hda1 in FILO, /dev/sda1 in Linux), but you currently have to use acpi=off or pci=noacpi. | ||||||
On-board SCSI | N/A | |||||||
On-board USB | OK | Tested: USB thumb drive in all 4 backpanel USB ports, as well as on the USB pin headers on the board (USB6_7, see manual). | ||||||
On-board VGA | OK | You need to prepend the VGA blob from the proprietary BIOS for this to work. Console works, X11 works (use the intel X.org driver). | ||||||
On-board Ethernet | WIP | The eth1 interface (in this case) works fine, but so far ifconfig -a only shows one of the three NICs (?) | ||||||
On-board Audio | WIP | Doesn't seem to work, yet. | ||||||
On-board Modem | N/A | |||||||

Miscellaneous | ||||||||
Sensors / fan control | OK | Works fine using the w83627hf and coretemp Linux kernel modules. | ||||||
Hardware watchdog | OK | Not yet actually tested, but it seems to be found: iTCO_wdt: Found a ICH7 or ICH7R TCO device (Version=2, TCOBASE=0x0560). | ||||||
SMBus | ? | |||||||
CAN bus | N/A | |||||||
CPU frequency scaling | ? | |||||||
Other powersaving features | N/A | |||||||
ACPI | ? | |||||||
Reboot | ? | |||||||
Poweroff | ? | Needs ACPI, thus won't work if you use acpi=off on the Linux kernel command line. | ||||||
Suspend | Unknown | |||||||
Nonstandard LEDs | N/A | |||||||
High precision event timers (HPET) | OK | The HPET is detected by Linux (hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0) and powertop output suggests that it works ok. | ||||||
Random number generator (RNG) | N/A | |||||||
Wake on modem ring | N/A | |||||||
Wake on LAN | Untested | The board should support WOL according to the manual. | ||||||
Wake on keyboard | ? | |||||||
Wake on mouse | ? | |||||||
TPM | Unknown | |||||||
Flashrom | OK | Works fine, but you have to use -m kontron:986lcd-m when booted with the vendor BIOS (not needed when booted with coreboot). |
Build tutorial
$ svn co svn://coreboot.org/repos/trunk/coreboot-v2 $ cd coreboot-v2/targets $ ./buildtarget kontron/986lcd-m $ cd kontron/986lcd-m/kontron_986lcd_m
Now copy your payload into the current directory and name it payload.elf. Then:
$ make -s
The resulting coreboot.rom is your coreboot ROM image you can flash using flashrom.
Notes
- If you use FILO, SATA will probably be hda and hdb, while hdc is the master drive of the IDE controller.
- Currently you have to use acpi=off on the kernel command line to make IDE work.
- If you experience kernel crashes try to blacklist the agpgart and intel_agp kernel modules.
- TODO: Add notes for proper (onboard) VGA setup.
